To @ZZ whom it may concern.:

Beit known that we, GEORGE SPENCER FRYA and SAMUEL LEWIS VALKER,citizens of the United States, residing at Loogootee, in the county ofMartin and State of Indiana, have invented a new and useful Spoke-SaWingMachine, of which the following is aspecification.`

This invention relates to spoke sawing machines; and it has for itsobject to effect certain improvements in sawing machines of thischaracter whereby the greatest possible amount of stock may be cut ontof asingle log.

To this end the main and primary object of the present invention is toconstruct a machine of the character noted with a variety of differentadj ustments to secure accurate work,

while at the same time with the least possible` amount of labor to theoperator, and with this in view the machine contemplates the cutting ofblank spokes in any desired sizes or lengths. With these and otherobjects in view which will readilyappear as the nature of the in,-vention is better understood, the same consists in the novelconstruction, combination and arrangement of `parts hereinafter morefully described, illustrated and claimed. g

In the accompanying drawingsz-Figure l is a front elevation of a spokesawing machine constructed in accordance with this invention. Fig. 2 isarear elevation ofthe same. Fig. 3 is an end view of the machine. Figliis a vertical transverse sectional "iew on the line x-x of Fig. 1. Fig.5 is a detail in perspective view of` the log carriage. Fig. 6 is anenlarged detail sectional view of the feed clutch on the carriage. Fig.7 is a detail sectional view at oneend of `the machine, the sectionincluding the gearing for the elevator. Fig. 8 is an enlarged detailview of the clutch gearing at the center and top of the log carriage.Fig. 9 is an enlarged detail sectional View at one end of thelog-carriage. FigflO is a detail sectional view on the line y-y of Fig.9. Fig. l1 is a detail sectional View at one side of the vertical sawarbor.

Referring to the accompanying drawings, the numeral l, designates thesill frame ofthe machine comprising opposite connected side pieces, andsupported on the sill frame l are the frame uprights 2, to the upperends of which are connected the longitudinal parallel track stringersi3the`in`ner of which is higher than the outer and to lboth of thesestringers are secured the metal track rails4, the inner of which issecured in a vertical position to one side of the track stringer, andprojects slightly above and below the same for the purpose to behereinafter described. The frame nprights to which the inner of thetrack stringers 3, is secured at one side, are extended above this trackstringer to form an elevator frame 5, extending nearly the entire lengthof the sill frame l, and at one side of4 the same, and this elevatorframe will be hereinafter more particularly referred to, but at thispoint it isto be noted that the track consisting of the rails 4, islocated at one side or in front of the said elevator frame.

At a suitable intermediate point on the frame l, is secured a stationarysaw frame 6, consisting of a base portion 7, andan upright portion S,this saw frame being suitably bolted to the sill frame 1, and also tothe front track stringer and to the elevator frame by means of suitablebracing connections 9. The upright portion 8, of the saw frame isadapted to adjustably support in position at upper opposite ends thereofthe vertically adjustable aligned bearing boxes l0, provided with theslotted attaching plates 1l, adj ustably bolted to the saw frame on thecombined clamping and adjusting bolts 12, and said opposite bearingboxes are connected by intermediate frame pieces 13, which insure the`alignment of both bearing boxes and complete a vertically adjustablebearing frame. Said vertically adjustable bearing frame forms a journalsupport for the saw arbor 14, to one end of which is removablyclampedthe vertical circular sawl, which is disposed at a central point betweenthe spaced track rails, While to the other outer end of the horizontalarbor 14, is secured the belt pulley 16, over which passes one end of adrive belt` 17 receiving motion from a belt wheel 18, mounted on one endof a transverse drive shaft 19, journaled in opposite bearing boxes20,10- cated at one end of the sill frame 1, and on the end of the driveshaft 19, opposite the belt Wheel 18, is mounted a band wheel 21,

ICO

which receives a belt from an engine or other motor designed tocommunicate motion to the several working parts of the sawing machine.

Adjustably attached'at one side of the upright saw frame 6,near to thevertical saw 15, is a laterally and an gularly adjustable bearing frame22. The adjustable bearing frame, or more properly speaking bearingplate 22, is

of a bowed shape and is provided at its upper and lower extremities withthe vertically aligned bearing boxes 23, which accommodate the verticalsaw shaft or arbor 24, to the upper end of which is fitted thehorizontal circular saw 25, disposed at one side of the vertical saw 15,and adapted to cut on a line coincident with the cutting line of thesaid Vertical saW in order that a blank spoke may be cut out of a pieceof stock fed longitudinally onto both of said saws. The said verticalsaw arbor 24, has mounted at an intermediate pointthereon, between thebearing boxes 23, a vertical belt pulley 26, over Vwhich passes theinner end of the drive belt 27, which is driven from the belt wheel 28,mounted at an intermediate point on the drive shaft 19.

At the upper and lower ends of the bearing plate or frame 22, the sameis provided at both sides of the vertical shaft or arbor 24, with thehorizontally disposed adjustment slots 29, which receive the bolts 30,that pass through and engage in the curved or inclined slots 31, formedin upper and lower portions of the saw frame 6, and providing means forthe angular adjustment of the horizontal saw 25. While ordinarily thehorizontal `saW 25, is rotated in a substantially horizontal plane,

` it will be obvious that it is necessary to'give a pitch or angle -tosuch saw in cutting out blanks from a circular log of wood, and byreason of the several adjustments, the proper relative positions of thevertical and horizontal saws may be always maintained with res'pect tothe center of the log being operated upon, and with respect to eachother, so that the nearest adjacent edges thereof will-cut on the sameline and therefore completely sever or separate the blank strip from thelog stock.

.Arranged to travel on the track rails, and directly over the two sawswhich are located between the ends of the track,`is a longitudi. nallymoving log carriage 32. The log carriage 32, is provided with a truckframe 33, consisting of opposite connected side and end bars, and ateach corner of said frame the same is provided with the bearing brackets34, depending therefrom and provided with open bearing notches 35, intheir lower edges to loosely receive the bearing spindles 36, projectedfrom both sides of the carriage rollers 37, that travel over said trackrails 4, and the inner pair of carriage rollers 37, are peripherallygrooved to engage the upper edge of the inner one of the track rails 4,to prevent the carriage from slipping out of posiu tion, and thecarriage is additionally secured on the track by means of a pair ofretaining arms 38, extended from the inner side bar of the truck frame33, and provided with lower hooked` ends 39, embracing the lowerprojecting edge of the inner track rail, and thereby effectuallypreventing the carriage from leaving the track.

The inner ends of the opposite end bars of the truck frame 33, areangled as at 40, to Y bring the inner pair of rollers on the higherinner track, which disposition is necessary to 1 provide for the properdisposition of the horizontal saw 25, and for the carrying of the logstock thereover, and arranged for transverse adjustment on top of thetruck frame 33 is the transversely adjustable supporting frame 41. Thetransversely adjustable supporting frame 41consists of the oppositesliding end bars 42, having inner angled endsV 43, connected by theinner side bar 44, the opposite extremities of which slightly overlapthe inner ends of the truck frame end bars to properly support the saidsupporting frame for a sliding movement, and the front ends of thesliding end bars 42, move under the'opposite guide plates 45, secured toopposite front corners of the truck frame 33, and journaled between thesaid opposite guide plates and the front side bar of the frame 33, arethe Vbearing rollers 46, against which works one edge of the end bars42, to ease the sliding movement of lsaid transversely adjustablesupporting frame and relieve the same from undue friction.

The opposite sliding end bars 42, of the frame 4l, have attached to theunder side thereof the pivot brackets 47, to which are pivotallyconnected the inner ends of the adjusting arms 48, provided with outerslotted ends 49, into which adjustably work the set screws 50, thatsecure in position within the outer slotted ends of said adjusting armsthe crank arms 51,bent from each end of the front adjusting rock shaft52. The adjusting rock shaft 52, is arranged longitudinally of the truckframe of the log carriage, and is journaled in the aligned bearing eyes53, projected from the front side bar of the truck frame. The said rockshaft is provided with a centrally arranged lever or handle 54, which ismanipulated to rock the shaft and thereby move the transverselyadjustable supporting frame either in or out to adjust the log stock toand away from the saws as the particular stage of the work may demand.

The transversely adjustable supporting frame 41, supports at oppositeends thereof the opposite pairs of vertical supporting rods 55,connected at their upper ends by the parallel longitudinal connectingbars 56, and the transverse guide frames 57, directly connecting thepairs of rods at each end of the supl porting frame, and said guideframes 57, are

provided with the vertically aligned guide openings 58, and one of saidguide frames is further provided at one side with a perforated bearinglug 59, the function of which will be presently described. Thevertically aligned guide openings of the bearing frames, located IOC IIO

at the upper ends of the opposite pairs of supporting rods 55,accommodate therein for vertical adjustment the upper threaded ends ofthe vertical adjusting rods or shanks 60, which are secured at theirlower ends to the sliding cross heads 61, provided at their oppositeextremities with the slide collars 62, loosely working on the supportingrods 55, and the vertical adjustment of these cross heads is securedfrom the interiorly threaded sprocket nuts 63, which engage the upperthreaded ends of the rods or shanks 60, and are supported in positionbetween the vertically aligned guide openings 58 of the opposite topguide frames 57.

Motion is communicated to the interiorly` threaded sprocket nuts 63, bythe endless adjusting chains 64, passing there-around and driven fromthe upper and lower superposed chain wheels mounted on a short verticaladjusting shaft 66, journaled in vertically aligned bearing openings 67,formed in the intermediate bearing frame 68, bolted on to' thelongitudinal connecting bars 56 atan in-` tel-mediate point.

The lower of the chain wheels 65,is fast on the shaft 66, and the upperof said wheels is loose on said shaft, but both ofsaid wheels areprovided at their adjacent sides with the clutch hubs or faces 69, whichare normally held in engagement with each other by means of the spring70, arranged ou the shaft 66,

fover the upper one of Asaid wheels to normally provide for thesimultaneous turning thereof, and to the lower end of the shaft 66, atthe bottom of the frame 68, is attached the horizontal beveled gearwheel or pinion 71, which is engaged by a vertical beveled gear pinion72, mounted on the inner end of the short operating shaft 73, journaledin the horizontal bearing 74, extended from the front lower side of theframe 68, and the outer end of said shaft 73, is extended into a cranklever or handle 74', which is turned in either direction as it may bedesired to adjust the cross heads 6l, up or down.

Normally, both of the cross heads 61, are adjusted by the rods or shanks60,similtane ously, but the character of the log at times demands adifferent adjustment for the cross head which carries the adjustablecentering device, and to provide means for securing the separateadjustment, the upper one of the chain wheels 65, is adapted to belifted out of engagement with the lowerone ofsaid chain wheels by meansof theliftingarms 75, which form a yoke extended from 'one side of theshort gear shaft 76, journaled between the opposite bearing lugs 77,projected from one side of the bearing frame 68. A gear lever 78, isextended from one end ot' the shaft 76, and by depressing on the outerfree end of this lever the upper one of said chain wheels 65, will belifted out of engagement with the lower one of said wheels in order thatthe adjustment of one of said cross-heads may be effected separately.

' A bearing frame 78', is extended from one side of one of the crossheads 61 and the rod or shank 80, connected thereto, and said bearingframe 78', carries at its outer end the bearing lug 79, in which isjournaled the outer end of the short turning shaft 80, the other end ofwhich turns in a bearing S1, at the under side of the cross headreferred to, and from the inner end of said turning shaft 80, isprojected the fixed centering pin S2, that is adapted to engage one endof the log at the center thereof, and at the base of said xed centeringpin is arranged a toothed clutch collar 83, which engages firmly in oneend of the log so that by turning the shaft 80, the log must necessarilybe turned therewith in order to properly shift the position of the` sameas the operation of sawingis continued around the log stock.

A worm pinion S4, is attached to or mounted on the shaft 80, near theouter end thereof and is engaged` by the adjusting worm 85, mounted onthe short adjusting shaft 86, jonrnaled in horizontal bearings 87, onthe frame 78', and provided at one end with a crank 88, for adjustingthe same. j

'An offstanding supportingbracket 89 is secured to the cross-head andthe adjusting rod or shank thereof opposite the fixed centering pin 82,and is provided at its outer end with a guide opening 90, aligned with asimilar opening 91', formed in the lower end of the adjacent rod orshank 60, and these aligned guide openings accommodate therein forlongitudinal movement thelongitudinally adjustable and movable thrustbar 91. longitudinally adjustable and movable thrust bar 91, is providedat its` inner end with the centering pin 92, which is opposed to the pin82, and is adapted to be thrust into one end of the log stock toproperly center and support the same in position, and these twocentering pins are adapted to be arranged in a line with or in the samevertical plane as the saw l5, when the frame 41, is adjusted in- Ywardas far as possible, and this relative position of the centering pins andthe vertical saw is necessary to secure the greatest possi ble amount ofstock out of the log.

The thrust bar 91, is provided in its upper edge with a series oflocking notches 93, and loosely receives thereon the longitudinallymovable latch sleeve 94. The latch sleeve 94, is prevented from beingmoved oii of the outer end of the thrust bar by the stop flange 95,attached to the outer end of said bar, and

said sleeve is provided in its top with the i latch openings 96, at eachside of which are located the bearing lugs 97, between which are pivotedthe inner ends of the lock latches 98. The lock latches 98 are providedwith the upwardly extending adjusting handles 99, and are adapted tohave their inner ends moved into the latch openings 94, and intoengagementwith the locking notches 93 of the thrust bar 91, and byadjusting the latch sleeve 94, longitudinally on the thrust bar The il'OO IIO

- end thereof to the angle of ahorizontally arranged bell crankadjusting lever 102, the inner extremity of which is pivoted at 103, toone side of the supporting bracket 89 near kor at the outer end thereof.By moving the bell crank adjusting lever 102, horizontally, in Aeitherdirection the thrust bar 91 may be moved against and away from one endof the log.

It is necessary to carry the log carriage, which has been described indetail, automatically over the sawsl and 25, and to provide for this Isecure to the carriage a feed clutch which I shall now proceed todescribe. A substantially rectangular bearing bracket 104, is secured atits lower end to one inner corner of the truck frame 33, of the logcarriage and has journaled therein the upper and lower horizontal feedshaft-s 105, carrying upon their outer ends at one side of the bracketsthe feed chain or sprocket wheel 106, and having mounted thereony insideof the bracket the friction disks or rollers 107, which are' distancedapart slightly greater than the length of the friction block 108,arranged there-between and mounted to slide in the bracket 104. Thefriction block 108, is provided with upper and lower notched clutch ends109, that are adapted to embrace one of said friction disks or rollersat a time, and said block is secured to the vertically adjustable sleeve110, embracing and sliding on one side of the bracket 104 and. havingpivotally connected thereto the lower end of the adjusting link 111. Theadjusting link 111, is provided with an upper yoked end 112, embracingthe upper end of the bracket 104, and has pivotally connected theretothe inner crank-end 113, of the horizontal adjusting shaft 114, theinner end of which turns Y in the bearing lug 115, projected from theupper portion of the bracket 104, embraced by the yoke 112. The shaft114, also loosely works in the perforated bearing lug 59, of one of theframes 57, and has attached to the outer end thereof the downwardlyexending operating lever 116. By moving the lever 116, to the right orto the left the friction block 108, will be moved tightly against eitherthe upper or lower friction disk or, roller 107, so as to clutch or holdstationary either one of the horizontal feed shafts 115.

The bearing bracket 104, is provided at the inner side thereof with theoppositely extending spindle arms 117, carrying at their outerextremities the spindles 119, on which are loosely mounted the spacingrollers 120, which loosely work between the upper and lower horizontalportions of the endless feed chain 121, and serve'to hold thel upperportion of the chain into engagement with the lower side of the upperone of the chai-n feed wheels 106, and the lower portion of said chaininto engagement with the lower one of said chain feed wheels 106, sothat when the upper one of the shafts 105, is locked fast by the meansdescribed, the log carriage will be moved in the direction of travel ofthe upper portion of the said feed chain, and vice versa. The saidendless feed chain 121, is driven from the drive sprocket wheel 122,mounted on one end of the chain shaft 123, journaled horizontally inaligned bearings 124, secured to one end of the elevator frame 5, and atau intermediate point on this shaft is mounted the beltwheel 125, overwhich passes the drive belt 126, which is driven by the belt pulley 127,mounted on the shaft 19, and through these gear connections the endlessfeed chain 121, is driven at the proper speed to provide forautomatically moving the carriage back and forth over the track.

At a point opposite the location of the drive sprocket wheel 122, theendless feed chain 121, passes over a chain or sprocket wheel 128, tocommunicate motion to the automatic gearing for the elevating devices,which will now be particularly referred to. The chain or sprocket wheel128, is. mounted on the front end of the short drive shaft 1 29,journaled transversely in the adjustable bearing blocks 130. The bearing,blocks 130, are provided with the squared openings 131, which looselyembrace the squared bracket arms 132 secured to one end of the elevatorframe 5, and standing olf therefrom. The said bearing blocks 130, may beadjusted to and away from the` end of the elevator frame 5, on thebracket arms 132 and are held fast in their adj usted positions by meansof the set screws 132', working in threaded openings in the `lower sideof said bearing blocks and adapted to vimpinge against the under side ofthe bracket arms 132. It will be obvious that this adjustment of theopposite bearing blocks 130, provides means for maintaining oradjusting'the endless feed chain 121, at the proper tension.

The short drive shaft 129, carries at a point between the adjustablebearing blocks 130, a small cog wheel or pinion 133, that is normallyout of engagement with a similar cog wheel or pinion 134, mounted at anintermediate point on the counter drive shaft 135, normally supported ina position above the shaft 129, so as to normally hold the cog wheel orpinion 134 out of gear with the wheel or pinion 133. The oppositeextremities of the counter drive shaft 135, are arranged to work in theslotted upper ends or extensions 136 of the bearing blocks 130, and arejournaled in the bearing collars 137 at the lower ends of thespring-supported pins 133, loosely work- XOO- IIO

position but are also saaeeeV ing through perforations 139, in the topelids of the bearing blocks 130, and provided with upper threadedportions to receive the ad-` justing nuts 140, which holdin position onsuch upper portions of the pins the supporting springs 141, arrangedbetween the nuts and the top of the bearing blocks, and said nuts notonly serve to secure the springs in provided for adjusting the tensionthereof.

The supporting springs 141 normally elevate the shaft 135, and looselyfitted at their upper ends on the said shaft 135, are the oppositelyarranged curved adjusting links 142, the lower ends of which arepivotally connectedat 143, to opposite sides of the swinging adjustingyoke 144, which yoke is 'provided at its upper or fixed end with thesleeves 145, loosely turning on the shaft 129, at both sides of thewheel or pinion 133, and extended inwardly from the swinging end of theyoke 144 1s the trip arm 146, to an intermediate point of which ispivotally connected the upper end of the connecting rod or wire 147, thelower end ofwhich is pivotally connected to the outer extremity of therock arm 149. The rock arm 149, is secured to the inner end of theadjusting shaft 148, mounted transversely at one end of the machineframe, and at the outer end of said shaft the saine is provided with thepress-arm 150, which is depressed to swing the moving end of the yoke144 downward, and cause the links 142, to lower the `shaft 135, andbring the wheel or pinion 134, into engagement with the wheel or pinion133,

and thereby cause motion to be transmitted to the shaft 135, to` turnthe chain wheel 151,

mounted on one ond of the said vertically movable counter drive shaft.The chain wheel 151, gives motion to an endless chain 152, which alsopasses over a chain or sprocket wheel 153, mounted on one end of thewinding shaft 154. The windingshaft 154, is journaled in the bearingboxes 155, mounted on top of the elevator frame 5, and said windingshaft carries the winding drum 156, on which winds and unwinds theelevating rope 157, which is secured fast at its other end to the top ofthe elevator frame and passes under the elevator pulley 157', secured tothetop of the guide frame 158, arising from the elevator platform 159,on which a log is adapted to be placed and be elevated up into the logcarriage to a position convenient for engaging the centering pins withthe log.

The elevator platform may be of any suitable constriiction, eitherslatted or tloored over and suitably braced to the guide frame 158,thereof, which moves at one side of the inner track rail and worksbetween the metallic guide flanges 160, secured to and projecting beyondone side of certain of the upright frame pieces of the elevator frame 5.

The elevator just described works ybeneath.

and up to the track on which the log carriage runs, and after thegearing for elevating the elevator has been thrown into gear bydepressing the press arm 150, the elevator will continue to be lifted upwith the log thereon until the trip pin 161 engages under the eX- tendedtrip arm 146. The trip pin 161 is projected from one side of the tripplate 162, provided with the vertically disposed slots 163, to receivethe screws i164, adjustably securing the said plate to one side of theguide frame 158. As the trip pin 161 comes in contact with the trip arm146, this trip arm throws the moving end of the yoke 144 upwardly andallows the springs 141 to liftthe` shaft 135 out of gear with the shaft129, which immediately and automatically stops the upward travel of theelevator, and the elevator is prevented.

from descending by means of the check pawl 165.

The check pawl 165, is pivoted at 166, to the front side of the elevatorframe 5, on the top portion thereof, andis adapted to have theengagement or point end thereof work on the ratchet disk or Wheel167,secured to one end of.

the winding shaft 154. The other end of the pawl 165 is reduced andloosely projects through a perforation or opening 168, in thespring-supported rod 169. The upper end of the spring supported rod 169,is threaded to receivethe nut 170, under which is placed the supportingspring 171, resting on the perforated bracket 172, through which workssaid rod 169, and which is secured to one top end of the elevator frame5. The lower end of the rod 169, is pivotally connected to the shaftarin 173, projected from one` end of the operating shaft 174, journaledtransversely of the main frame of the machine at one end thereof andprovided at its outer end with a lever arm 175. Normally, the spring171, holds the pawl 165 in engagement'with the ratchet disk or wheel167, to prevent the backward rotation of the winding drum after theelevator has been raised, but when it is desired to lower the elevator,it is simply necessary to depress the lever 175, which movement willrelease the pawl 165, from the ratchet disk or wheel and allow theelevator to automatically lower to the sill frame.

The log which is centered between the centering pins of the log carriageis usually marked oft' at the end which moves onto the saws, but notnecessarily so, and after each cut of a blank spoke out of the saine itis necessary to turn the log a certain distance for the next succeedingcut, and the proper turn `of the log is regulated or limited by the`gage arm 176, which carries at its ou ter end` the gage roller 177,against which the log bears as it is carried onto the saws, and saidgage arm 176, is projected from the upper end of the gage rod 178,loosely mounted in the vertically aligned bearing openings 179, formedat an intermediate point in the gage frame 180. The lower one of saidbearing openings is formed in the lower end of a depending bracket 181,on which is supported the turning spring 182, connected with the rofl178, and bearing at one end against said IOO IZO

bracket in order to normally project the gage arm 176, to the front andin the path of the log, said gage arm normally resting against the stopange183 formed at one upper side of the gage frame. By reason of thespring connectionA with the gage rod, the same will freely turn in thedirection of the travel of the log carriage as it moves over the saws tocut the log, and after the log has passed the gage the spring willimmediately throw the gage arm 176, back to its normal front position,and any tendency to depress the gage arm and rod is readily yieldedto'inasmuch as the said gage rod has a vertical movement 1n thevertically aligned openings 179, and is limited in this movement andproperly adjusted with respect to the centers of .the log carriage bymeans of the adjusting nut 184, engaging the lower threaded end 185, ofsaid gage rod and working under the bracket 181.

The gage frame 180, is provided at one side of the gage rod supportedkthereby with the Aupper and lower supporting rods 186, ar-

ranged to slide in the guide openings 187, formed in one of the uprightsof the elevator frame, and projecting forwardly in a direction oppositeto the rods 186, is the adjusting arm 188, having an outer threaded end189, on which works the adjusting sleeve 190, mounted to loosely turn inthe bearing collar l191, secured to the front side of the upright sawframe 6, and said adjusting sleeve is interiorly threaded and isprovided at its outer end with a hand wheel 192, which provides meansfor conveniently adjusting the gage frame in and out to properly adjustthe positlon of the gage rod and the arm carried thereby.

In operation, the log carriage is placed in a position on the trackdirectly over the elevator, withl its thrust bar retracted out-of theway of the log to be elevated.' The log to'be lelevated is rolled ontothe platform of the el evator, and by depressing the -press arm 150, thegearing for the elevator is thrown into gear in a manner alreadydescribed, and the log will be elevated into the log carriage in aproper position to be grasped by the centering pins thereof, and atabout this time the'automatic trip devices will throw the gearing forthe elevator out of gearto stop the elevator and hold the samestationary. By properly adjusting the vertical adjustment of thecentering devices on thelog carriage and engaging the Opposite centeringpins at the end centers of the log, the same will then be supported inYa position for being fed onto the saws.v The elevator is then dropped bydisengaging the check paWl herein referred to. In making the rst cut itis necessary to move the log to the front side of the center of the 10gcarriage and therefore bring its center out of alignment with thevertical plane of the vertical saw 15, and this is accomplished byraising the lever or handle 54, to adjust the supporting frame 41, whichcarries the centering devices, toward the front.

In the meantime the. carriage remains stationary, inasmuch as the feedchain 121 freely turns the chain feedfwheels 126,but by moving the lever1l6.to the left the lower one of the wheels 106, will be clutched ontothe lower portion of the chain 121, so that the carriage will be carrieddirectly over the saws which will cutout the rst strip. After thismovement the lever 116, is moved to the right to clutch the upper one ofthe `wheels 106, on

` the upper part of the chain 121,so as to move the carriage back to itsstarting point, after which the lever 54, is moved downward to bring thecenter of the log in line with the vertical saw or line of cut, and thecarriage moved over the saws to cut out the first spoke blank, it beingunderstood that the first movement of the log over the sawswas to cutout the rst slat or strip. After the carriage has been again returnedthe log is turned by the turning device herein described, until itcontacts with the gage which determines the proper adjustment for thenext cut, and this operation is repeated until all the stock possible iscut out of the log, it being understood that the log is adjusteddownward as the operation continues.

Changes in the form, proportion and the minor details of constructionmay be resorted to withoutdeparting from the principle or sacriicing anyof the advantages of this' invention.
